Dynamic Lov in Tablular Report

We have been working on a tabular report region within a master-detail form where the values populated in a drop down field are based on the value chosen from previous field. Thought we saw info on how to do this with javascript (without submitting the form from the previous field) earlier on this forum, but we can't find it now. Have read several posting dealing with AJAX but thought this one only included javascript. Any help would be appreciated.
Thanks,

Dynamic LOV based on report column

HI,
I've a standard report with Two columns. Column1 is standard Report Column and Column 2 is a LOV based on an SQL Query.
Now I need to filter the LOV (add a where clause) based on the value in the column1.
For example, consider Column1 as "country" and column2 as "state". so the in column2(LOV), user should see only the list of states belongs to the corresponding country(Column1)
Please note that the report is based on an SQL query
Any clue on how to do this.
I'm using APEX4.1.
Thanks in advance

Dynamic lovs in parameter forms ... Is this possible?

Hi
I am using report developer 10g on windows xp.
I need a cascading prompt style dynamic LOVs in my report parameter form.
The first LOV displays a set of values (say for eg. dept list). The second LOV will display another list, based on the value chosen by the user in the first LOV (Eg. List of employee names in that dept).
My first LOV select statement may look like below for the user parameter say P_DEPT
select deptno from dept;
My sencod LOV select stmnt may look like below for the user parameter P_EMP
select ename from emp where deptno = :P_DEPT
Each time I try to set the second LOV, report developer complains "Bind variables not allowed in select statement"
Same error msg comes if I reference the first user parameter(P_DEPT) as a lexical parmaeter.
How do I acheive the above in report parameter form? Any help is appreciated greatly...
Thanks

Hi Brad,
Thanks for the reply. I had almost given up hope on receiving replies to this message.
I do agree that it is simpler (and a lot striaght forward) to just use forms to develop dynamic LOVs of cascading prompt style, that is required in my app. But in our shop, we have integrated forms and reports in such a way, that all the report parameters are handled by report developer's own parameter form, rather than coding a separate logic on the forms side to handle the report parameters(as this has to be done on the forms side for every report that we generate, We thought it would be better to use the reports developer to handle the parameter input and then pass the .rdf to forms app). Currently in all our app, the parameter form generated by the report developer is rendered as HTML form on the browser (when the concerned rdf file is called within the forms app) and by submitting this we get the report output)
Hence I am very keen to get this done somehow on the report developer side.
I do hope I get some input on this. Also, its a little surprising that such a simple feature is not readily avalibale in the report parameter form. I hope oracle report developer team is reading this message...:)
Thanks

How to make use of a static or dynamic LOV in Desktop Instelligence reports

I want to use static LOV as well as dynamic LOV as a prompt for one of my report.
I have created a dynamic LOV but I dont know how to include it as a prompt to my reports. Please teach me the same.
For example I have two classes called COMPANY and EMPLOYEE in my universe. Each entry in the company class will have n number of employees in the employee class. My requirement is when I run the report it should prompt the user to select the company name which is a object in the COMPANY class. Based on the users's input the report should pull the employee data.
For this I have to create a COMPANY name LOV and this should be used in the 'Conditions' section of the Desktop Intellegence.
Please guide me for the same.

Hi,
LEt me know where u need the prompt object to be created in UNV or in report level.
In Unv:
Select Company name object-> double click it and in Select clause define as below
@variable('1. Enter Company Name'')
In Report level: Go to Query panel select Company class object in where clause and select required operator as LIKE OR IN LIST OR NOT IN LIST OR DIFFERENT FROM and select prompt and give some prompt message.
Cheers,
Suresh Aluri.

Dynamic LOV in report based on universe

Hi experts,
I have found the following thread and I understand that I can change the registry to have dynamic LOV for BOXI R2:
http://scn.sap.com/thread/1524666
Is it possible for BI4.1?
Also is it possible for CR4E with .unx source?
Regards,
Gordon

OK. The Path for 4.0 would be:
32-bit machine:
HKEY_LOCAL_MACHINE\SOFTWARE\SAP BusinessObjects\Suite XI 4.1\Crystal Reports\Database
64-bit machine:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\SAP BusinessObjects\Suite XI 4.1\Crystal Reports\Database
And then create the string key per the suggestion in that thread.

QBE Report and Dynamic LOV

I have a QBE Report on a table "A" where the value of a field "F" is the "id", of another table "B".
For populating the table "A" I have create a form that uses a dynamic LOV (select name, id from B).
In the QBE report, the value of "F" is the id, instead of the "name". How can I display the name?
Moreover, if I "Update" a record, I would like to have (in the form for updating) the combobox with the complete LOV and NOT the text box with the id.
How can I do that?
thanks

Hi,
This happens in the case when a webview component has been added to a page and the mode selected is EXCEL. You see the excel dump on the screen.
This was a bug and has been fixed in 902.
Incase U want an excel report then you would have to use the RUN options available from the manage screen or navigator .This brings up a save option.You can open it or save the same and then open it.
Thanks,

Dynamic LOV in universe based report

Hi,
My question is simple.
In Crystal Reports ,is it possible to have a dynamic LOV for the prompts when the report is based on universe? When ever the user chooses the drop down in prompt page, he should see only his values in LOV. This works in WebI.
I read from the forum that in crystal, this can only be possible with Business View. Is this true?
If i use Business view and the user opens the report in Infoview, does he needs DSN to use the connection i have created in Business View to refresh the LOV dynamically?
Please suggest a solution for dynamic LOV as this started as a simple issue and i'm breaking my head to solve this!!

Once you create any dynamic parameter in crystal which is using direct database connection and if you publish that report to server then it automatically generates a list of values using business view in repository in which the business view uses the same connection what you have used for the report. Now when you try to run the report in info view first it prompts for LOV from repository. Before refreshing the LOV it prompts to connect to your database and if you don't want this prompt to popup everytime then open the connection in business view manager and in the properties select never prompt by giving the database credentials.
You can also create LOV using universe as datasource. To get the updated list you need to change the registry key settings like this
select the option Always refresh before use in the universe properties and change the registry like this
HKEY_LOCAL_MACHINE\software\business objects\suite 11.5\crystal reports\database\AlwaysRefreshUniverseLOV
Type: String
Recognized Values: Yes, 1

Dynamic lov, Select List in Report

Hi all,
I have searched the APEX forum for dynamic lov but somehow no topic could really solve my problem.
I have a report and 2 columns in this report are displayed as a select list. I want one of the select list show some values depending on the other select list in this report. If the value of the first select list is equal to some data the second select list should show a lov and otherwise nothing.
All examples i have found so far seem to explain a solution for a select list item on the page and not for a select list in a report like in my case.
Are there any advices or some links you can give?
Thanks in advance

Problem with dynamic LOV and function

Hello all!
I'm having a problem with a dynamic lov in APEX 3.0.1.00.08. Hope you can help me!
I have Report and Form application. On the Form page i have a Page Item (Popup Key LOV (Displays description, returns key value)).
When i submit the sql code in the 'List of vaules defention' box. I get the following message;
1 error has occurred
LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query.
When i excecute the code below in TOAD or in the SQL Workshop it returns the values i want to see. But somehow APEX doesn't like the sql....
SELECT REC_OMSCHRIJVING d, REC_DNS_ID r FROM
TABLE(CAST(return_dns_lov_fn(:P2_DNS_ID) AS dns_table_type)) order by 1
returns_dns_lov_fn is a function, code is below;

and the types;

I just had the same problem when I used a function in a where clause.
I have a function that checks if the current user has acces or not (returning varchar 'Y' or 'N').
In where clause I have this:
where myFunction(:user, somePK) = 'Y'
It seems that when APEX checked if my query was valid, my function triggered and exception.
As Varad pointed out, check for exception that could be triggered by a null 'p2_dns_id'
Hope that helped you out.

Creating a dynamic lov based on a column

Hi,
I want to create a dynamic lov based on a column in a database-table.
Eg. the query
'select code, description from code_table'
is the contents of the column 'lov_query' in the table 'parameters'.
For every parameter there can be a different lov-query, but the result is always
two columns (code and description, number and name, etc.), exactly what you need to use in a lov.
I've written a (dbms_sql) function that takes the parameter-id and returns the lov_query.
create or replace function "GET_PMR_LOV"
(pmr_id in NUMBER)
return VARCHAR2
is
cur INTEGER := DBMS_SQL.OPEN_CURSOR;
fdbk INTEGER;
l_pmr_id NUMBER(9) := pmr_id;
l_stmnt VARCHAR2(2000);
begin
DBMS_SQL.PARSE
(cur, 'select pmr.lov_query from parameters pmr where pmr.ID ' || ' = 'L_PMR_ID', DBMS_SQL.NATIVE);
DBMS_SQL.BIND_VARIABLE (cur, 'L_PMR_ID', l_pmr_id);
DBMS_SQL.DEFINE_COLUMN (cur, 1, l_stmnt, 2000);
fdbk := DBMS_SQL.EXECUTE (cur);
fdbk := DBMS_SQL.FETCH_ROWS (cur);
IF fdbk > 0
THEN
DBMS_SQL.COLUMN_VALUE (cur, 1, l_stmnt);
return (l_stmnt);
ELSE
return null;
END IF;
DBMS_SQL.CLOSE_CURSOR (cur);
END;
But now I'm stuck on how to pass on this statement in HTMLDB
as an dynamic lov, I don't seem to be able to execute this statement
into the two display and return columns. Any ideas?

Hello again,
This lov is on an updatable report-column where the user has to make a choice from an non-named, popup and query-based lov. In the lov-query box I have just put:
"return get_pmr_lov(:p41_param_id)" (without the quotes ;-)
Here's my latest version plus an alternative, which both seem to work fine:
create or replace function "GET_PMR_LOV"
(pmr_id in NUMBER)
return VARCHAR2
is
cur INTEGER := DBMS_SQL.OPEN_CURSOR;
fdbk INTEGER;
l_pmr_id NUMBER(9) := pmr_id;
l_stmnt VARCHAR2(1000);
begin
DBMS_SQL.PARSE (cur, 'select pmr.lov_query from paramaters pmr where pmr.ID ' || '= :L_PMR_ID', DBMS_SQL.NATIVE);
DBMS_SQL.BIND_VARIABLE (cur, 'L_PMR_ID', l_pmr_id);
DBMS_SQL.DEFINE_COLUMN (cur, 1, l_stmnt, 1000);
fdbk := DBMS_SQL.EXECUTE (cur);
fdbk := DBMS_SQL.FETCH_ROWS (cur);
IF fdbk > 0 THEN
DBMS_SQL.COLUMN_VALUE (cur, 1, l_stmnt);
return (l_stmnt);
ELSE
return null;
END IF;
DBMS_SQL.CLOSE_CURSOR (cur);
END;
create or replace function "GET_PMR_LOV2"
(pmr_id in NUMBER)
return VARCHAR2
is
l_pmr_id NUMBER(9) := pmr_id;
l_stmnt VARCHAR2(1000);
BEGIN
EXECUTE IMMEDIATE 'select pmr.lov_query from parameters pmr where pmr.ID = :1'
INTO l_stmnt USING l_pmr_id;
return l_stmnt;
END;
The error-message remains the same, unable to bind :p41_param_id !

Two LOVs in same report customization form causes problems

My report includes two parameters which are set by the user using dynamic LOVs in the customization form. The report used to only have one parameter and this worked fine. After including the second one only one of the LOVs work as they should. The second one doesn't trigger a value to be sent to the report. Working separately the second parameter/LOV also works as it should.
The code:
SELECT distinct ID, STILLING, F_DATO, STILLING_NAA, DATO
FROM JOBBSOKNADER
WHERE STILLING in :lov_stillinger
union
SELECT distinct A.ID, A.STILLING, A.F_DATO, A.STILLING_NAA, A.DATO
FROM JOBBSOKNADER A, JOBBINT_KOBL B
WHERE A.ID = B.JOBBSOKNADER_ID
AND A.STILLING = '(apen soknad)'
and B.INT_ID in :lov_interessefelt

Hi,
Are you trying to use dependant LOVs i.e second LOV depends on the value selected in the first LOV. If you are trying that, then reports does not support that. You have this facility only in forms.
If I have understood wrong, then please give me the query you used for the LOVs
Thanks,

Thanks for Your help.
The date is in fact a CHAR display (not really a date) so that is not the error.
For your information when i select a row in the list (format char YYYYMMDD_HHMM) it seems that Apex do not catch my select in the Session state.
I've change the item name with P2_DATE_FLOW but the problem remain.

Selecting both static and dynamic values in a report.

Hello,
I am using the following LOV for a select list in a form based on another post (Re: Static and Dynamic LOV ordering
It is presenting five static values along with a dynamic LOV.
select d, r
from (select n, d, r
from (select 1 as n, 'NAME_A' d, 1 r
from dual
union all
select 1 as n, 'NAME_B' d, 2 r
from dual
union all
select 1 as n, 'NAME_C' d, 3 r
from dual
union all
select 1 as n, 'NAME_D' d, 4 r
from dual
union all
select 1 as n, 'NAME_E' d, 5 r
from dual
union all
select 2 as n,
(LNAME || ', ' || FNAME || ' (' ||
to_char(DOB, 'MM/DD/YYYY') || ')') display_value,
ID return_value
from my_name_table)
ORDER BY n, r asc)
The static display and return values do not exist in my_name_table, but the static return values are recorded in my_main_table when the user submits the form.
The tables look like this:
my_main_table:
record_id
name_id
my_name_table:
name_id
fname
lname
How can I present the display values associated with the static return values recorded in my_main_table along with the dynamic display values in a report? I am currently presenting the dynamic portion in a report using the following select statment:
select
(my_name_table.LNAME||', '||my_name_talbe.FNAME) AS Name
from my_name_table
WHERE my_main_table.NAME_ID = my_name_table.NAME_ID
I have the additional problem that the static return values are not in my_name_table so the join in the last statement will not find the static values in my_name_table.
Edited by: mterlesky on Feb 24, 2009 9:51 AM

1. You will need to add an outer join to return all the values in the Main table.
2. Then decode the values for the static LOV.
Something like (this is not tested, but should give you the idea)
select
decode(my_main_table.NAME_ID,1,'NAME_A',2,'NAME_B',3,'NAME_C',4,'NAME_D',5,'NAME_B',(my_name_table.LNAME||', '||my_name_talbe.FNAME)) AS Name
from my_name_table
WHERE my_main_table.NAME_ID = my_name_table.NAME_ID(+)
This will all break if any of your static LOV ID values clash with your dynamic LOV ID values.
I am now going to give you a long lecture about hard coding values ..... ;)

Problems using Dynamic parameters with Crystal Reports and SBO 8.8

Has anyone been able to successfully use a dynamic parameter in Crystal Reports with 8.8 using the Business One connector? When we try we get an additional logon to the database that pops up and the logon fails.
We need this because we want to return live lists of PO documents from the server for selection. We are also trying to use nested dynamic parameters, because we want to first return the PO document based on the PO number, and then chose specific rows based on a field value in POR1.
It works if we don't use the Business One connector, but then the report doesn't function properly inside of SAP.
Any ideas would be appreciated.

I have tried using tokens but they are too simple. I need something like a subselect where you first select one value and then another that is a subset of those values. Apparently the tokens can't even use a "where" clause.
SAP dances around Dynamic parameters, but won't come out and say that they can't be used with the B1 connector. If that is the case then they should just say so and stop wasting our time. Apparently Crystal is not truely interfaced with B1, just sort of hanging out with it.
I don't really care other than I have to do this select, subselect. If someone has a way to do that with tokens I would love to hear it.
Thanks,
Roy

Issue about dynamic lov

Hello exper,
I want to use dynamic lov for parameter. when editing this parameter, I select "dynamic" for lov, "account_id" for value. but no list of value for this parameter in the parameter dialogue. My data source is oracle stored procedure.
Many Thanks,

when you create the parameter you are selecting DYNAMIC, then you select the field to pull from
then you place the parameters in the record selection correct?
make sure you lov doesnt change when data is entered, they do not update themselves and require daily maintenance.
when you run your report does the value you are looking for show up, it will only display if it is in the dataset.
